Summary
Obesity and type 2 diabetes are nationally and globally reaching epidemic rates. This project investigates the regulation of blood flow within muscle and its impact on metabolism. Outcomes from the study may lead to diagnostic tools and treatments for cardiovascular disease associated with obesity, hypertension and type 2 diabetes.

Summary
This project will determine whether the bioactive compound in green tea (called EGCG) can reduce insulin resistance by enhancing the ability of insulin to open very small blood vessels (called capillaries) in muscle. Opening more capillaries will help glucose to be stored in muscle, thus alleviating insulin resistance. Findings from these studies may have important impact on the management of insulin resistance and type 2 diabetes.

Summary
A number of studies over recent years including our own have suggested that insulin acts in normal humans and animals to improve blood supply to muscle and that a contributing factor to Type 2 diabetes is an impaired ability of insulin to achieve this effect. Our key contribution to this field is the finding that insulin acts to alter blood flow in muscle to improve access for itself and nutrients such as glucose.

Our key contribution to this field is the finding that insulin acts to alter blood flow in muscle to improve access for itself and nutrients such as glucose. This discovery of blood flow redistribution in muscle was made possible by newly developed in-house methods. Using these methods we now wish to explore (a) the mechanism by which insulin mediates this effect and (b) when this effect of insulin to improve muscle blood flow is impaired in diabetes, how it might be recovered. We expect to find that insulin-mediated capillary recruitment in muscle results from a signal substance released from muscle that permeates nearby tissue reacting with the blood vessels to improve blood flow. It is also expected that new therapeutic approaches for enhancing insulin action in muscle and targeted at the blood vessels will be identified.Read moreRead less
